It is basically Alhanalem frozen in the "Crystal". It attacks with magic and can make use of the Ring Lock technique. It can also use the Yuke Tribe Ability Magic Thread, throwing a Fire Magicite on the floor to use with the Magic Thread to create a trail of fire that follows the player from the Magicite and can cause very serious damage, so it is advised to either moving out of the way quickly or taking the Magicite for yourself.

Of note, it can cast the Slow and Gravity spells in Multiplay, and in both modes, despite being unable to do so, standing on top of the boss will prompt it to try to cast Meteor on the player.

Stock up on Blizzards and Thunders before the battle. Once the battle starts, keep spamming with physical attacks and cast Blizzard or Thunder every once in a while. Avoid the Fire attack (as stated above) and grab the Magicite. You can either stock it or turn it back against him. Rinse and repeat (while healing occasionally) and the battle should be a snap.
